ABSTRACT

Introduction The current research sets out to assess implant early survival rates and identify relevant parameters. Methods The research spanned the years 2021 and 2022 and included all individuals who had dental implants. Various criteria, such as age, sex, maxilla/mandible, implant location, immediate implant, implant diameter, implant length, and others, were used to determine the implant survival rate in the research. A multiple logistic regression model was used to show the risk variables for early survival rates of implants, and components with p < 0.05 were further included after the Chi-square test was employed to filter them. Results The current research included 128 patients who had a single implant procedure, including 70 males and 58 females. The early survival rate was 91.40%, and 117 implants were retained after implantation. Risk variables that were shown to be associated with early survival rates were patients aged 30-60 years (OR: 2.542), immediate implant placement (OR: 3.742), and implant length less than 10 mm (OR: 3.972). Conclusions Age, tooth location, implant length, and immediate implantation were risk variables that contributed to our subjects' above 91% early survival rate of implants.

ABSTRACT

We revisit the well-known Gilbert-Varshamov (GV) bound for constrained systems. In 1991, Kolesnik and Krachkovsky showed that the GV bound can be determined via the solution of an optimization problem. Later, in 1992, Marcus and Roth modified the optimization problem and improved the GV bound in many instances. In this work, we provide explicit numerical procedures to solve these two optimization problems and, hence, compute the bounds. We then show that the procedures can be further simplified when we plot the respective curves. In the case where the graph presentation comprises a single state, we provide explicit formulas for both bounds.

ABSTRACT

BACKGROUND: In traumatic brain injuries (TBI), cerebral microdialysis (CMD)-derived parameters, especially the lactate to pyruvate ratio (LP ratio), have been utilized for cerebral perfusion optimization. The objectives were to identify cerebral ischemia as measured by CMD in TBI patients requiring decompressive craniectomy and to observe the correlation between cerebral perfusion pressure (CPP), intracranial pressure (ICP), and CMD variables in these patients. Our secondary aim was to observe the effect of CPP augmentation on ischemia biomarkers. METHODS: After the Institute Ethics Committee approvals, seven adult patients requiring decompressive craniectomy following TBI were enrolled and CMD data were obtained prospectively for 72 h. CPP was augmented by 20% with noradrenaline infusion if LP ratio >40. Correlations were done with bootstrapping (n = 500) to obtain the confidence intervals (CI) due to the small sample size. RESULTS: One patient had cerebral ischemia (median LP ratio of 265.5 and median pyruvate of 38 µmol/L), while another patient had non-ischemic mitochondrial dysfunction (median LP ratio 40.7 and median pyruvate 278.5). The coefficients of correlation between the LP ratio with CPP and ICP were r = -0.05 (CI = -0.14-0.03) and r = 0.09 (CI = -0.03-0.24), respectively. The coefficient of correlation between cerebral and blood glucose was r = 0.38, (CI - 0.35-0.14). Only two patients needed CPP augmentation, however, postaugmentation cerebral biochemistry did not change appreciably. CONCLUSION: CMD can identify cerebral ischemia, however, no correlations were observed between the LP ratio and CPP or ICP. CPP augmentation did not improve cerebral biochemistry. More studies are required to understand and treat cerebral metabolism in TBI.

ABSTRACT

Due to rising environmental and global public health concerns associated with environmental contamination, human populations are continually being exposed to environmental toxicants, including physical chemical mutagens widespread in our environment causing adverse consequences and inducing a variety of neurological disorders in humans. Physical mutagens comprise ionizing and non-ionizing radiation, such as UV rays, IR rays, X-rays, which produces a broad spectrum of neuronal destruction, including neuroinflammation, genetic instability, enhanced oxidative stress driving mitochondrial damage in the human neuronal antecedent cells, cognitive impairment due to alterations in neuronal function, especially in synaptic plasticity, neurogenesis repression, modifications in mature neuronal networks drives to enhanced neurodegenerative risk. Chemical Mutagens including alkylating agents (EMS, NM, MMS, and NTG), Hydroxylamine, nitrous acid, sodium azide, halouracils are the major toxic mutagen in our environment and have been associated with neurological disorders. These chemical mutagens create dimers of pyrimidine that cause DNA damage that leads to ROS generation producing mutations, chromosomal abnormalities, genotoxicity which leads to increased neurodegenerative risk. The toxicity of four heavy metal including Cd, As, Pb, Hg is mostly responsible for complicated neurological disorders in humans. Cadmium exposure can enhance the permeability of the BBB and penetrate the brain, driving brain intracellular accumulation, cellular dysfunction, and cerebral edema. Arsenic exerts its toxic effect by induction of ROS production in neuronal cells. In this review, we summarize the molecular mechanism and mechanistic effects of mutagens in the environment and their role in multiple neurological disorders.

ABSTRACT

Background and Aims: There are two approaches for ultrasound (US)-guided vessel cannulation: the short axis (SA) approach and the long axis (LA) approach. However, it remains to be seen which approach is better. Therefore, we performed the present updated systematic review and meta-analysis to assess the effectiveness and safety of US-guided vascular cannulation between the SA and LA techniques. Methods: We performed a comprehensive electronic database search in PubMed, Embase, Cochrane Library and Web of Science for the relevant studies from inception to June 2022. Randomised controlled trials comparing the SA approach and the LA approach for US-guided vascular access were incorporated in this updated meta-analysis. The first-attempt success rate was the primary outcome. The secondary outcomes were the overall success rate, cannulation time, number of attempts and the incidence of complications. The statistical analysis was conducted using RevMan software (version 5.4; the Nordic Cochrane Centre, the Cochrane Collaboration, Copenhagen, Denmark). The Cochrane risk of bias tool was used to evaluate each study's potential risk for bias. Results: In total, 16 studies consisting of 1885 participants were incorporated in this updated meta-analysis. No statistically significant difference was found between the SA and LA vascular access techniques for first-pass success rate (risk ratio = 1.07, 95% confidence interval: 0.94-1.22). The overall cannulation success rate, complication rate, average cannulation time and average number of attempts were not significantly different between the SA and LA groups. Conclusion: This updated meta-analysis demonstrated that the SA and LA approaches of US-guided vessel cannulation are similar regarding first-pass success, overall cannulation success rate, total complication rate, cannulation time and the number of attempts.

ABSTRACT

Environmental mutagens are chemical and physical substances in the environment that has a potential to induce a wide range of mutations and generate multiple physiological, biochemical, and genetic modifications in humans. Most mutagens are having genotoxic effects on the following generation through germ cells. The influence of germinal mutations on health will be determined by their frequency, nature, and the mechanisms that keep a specific mutation in the population. Early prenatal lethal mutations have less public health consequences than genetic illnesses linked with long-term medical and social difficulties. Physical and chemical mutagens are common mutagens found in the environment. These two environmental mutagens have been associated with multiple neurological disorders and carcinogenesis in humans. Thus in this study, we aim to unravel the molecular mechanism of physical mutagens (UV rays, X-rays, gamma rays), chemical mutagens (dimethyl sulfate (DMS), bisphenol A (BPA), polycyclic aromatic hydrocarbons (PAHs), 5-chlorocytosine (5ClC)), and several heavy metals (Ar, Pb, Al, Hg, Cd, Cr) implicated in DNA damage, carcinogenesis, chromosomal abnormalities, and oxidative stress which leads to multiple disorders and impacting human health. Biological tests for mutagen detection are crucial; therefore, we also discuss several approaches (Ames test and Mutatox test) to estimate mutagenic factors in the environment. The potential risks of environmental mutagens impacting humans require a deeper basic knowledge of human genetics as well as ongoing research on humans, animals, and their tissues and fluids.

ABSTRACT

Nanotechnology has been extensively exploited for its enormous therapeutic and diagnostic potential in the management of multiple disorders. It employs nanomaterials as drug carriers with enhanced efficacy and limited side effects on normal tissues. A lot of nanomaterials have been studied and produced, imminently reforming the treatment and diagnostics of numerous malignancies, including cancer. The purpose of the present study is to explore the role of nanotechnology-based devices/therapies that have a vital function in the therapeutics and diagnostics of cancer with potential impact at three levels: early detection, tumor imaging, and drug delivery methods. Concentrating on cancer, promising nanotechnology-based approaches have been planned to satisfy the need for targeted specificity of traditional agents of chemotherapeutics, in addition to early recognition of malignant and precancerous lesions. Prostate cancer is the fifth most wellknown cancer worldwide and the second most usually detected cancer in men. Therefore, there is a crucial need to improve therapeutic prospects for the diagnosis and treatment of prostate cancer via the exploitation of the potential of nanomaterials for cell-targeted specificity and improved primary diagnosis of precancerous tumors. The present review, therefore, focuses on summarizing all prospective applications of nanotechnology in the prognosis and diagnosis of prostate cancer, which would further help researchers to elucidate a more potent therapeutic approach for the better management of prostate cancer in the days ahead.

ABSTRACT

BACKGROUND AND AIMS: Posterior vessel wall puncture (PVWP) is a common complication of ultrasound (US) guided central venous cannulation. We evaluated and compared the frequency of PWVP of internal jugular vein using short axis (SA) and long axis (LA) approach of US-guided needle cannulation. As a secondary objective incidence of carotid puncture was assessed. MATERIAL AND METHODS: Prospective, single-blinded, cross over, observational study at Urban Level I Neuroanesthesiology and Critical Care Department. Residents receiving standard education on ultrasound-guided central venous cannulation were asked to place an US-guided catheter using either short axis or long axis approach on a human torso mannequin. During the procedure, the path of the needle was carefully observed by the investigator for any PVWP and carotid puncture without interference with the placement procedure. The confidence level of the resident for the intraluminal placement of the needle tip was measured on a 10-point Likert scale. RESULTS: Forty residents participated in the study. The incidence of PVWP in SA and LA group was 40% and 17.5% respectively and was statistically significant (p = 0.026). There was no incidence of carotid artery puncture in either of the group. The mean confidence of intraluminal placement of needle was significantly higher in the LA group (8.32) as compared to the SA group (5.95). CONCLUSION: Lower incidence of PVWP was seen in LA as compared to the SA approach during US-guided IJV cannulation in phantom in residents having previous experience of CVC (central venous cannulation) in landmark technique only. Participants were more confident about intraluminal needle placement in the LA group compared to the SA group.

ABSTRACT

Background All medical graduates must know how to stabilize and manage critically ill patients. A 2-day intensive course, called the acute critical care course (ACCC), was conducted to train interns in technical and non-technical skills for managing a patient whose condition is deteriorating. This analysis aims to assess the feasibility and effectiveness of ACCC for interns. Methods We developed and conducted the ACCC to train interns. It included lectures and skill stations. Twenty-four interns participated in the course. Immediate, post-course, quantitative and qualitative feedback was taken online. Qualitative information was also collected verbally and later by email. These data were analysed both quantitatively and qualitatively. Thematic analysis was used to identify, analyse and report the patterns of responses and behaviour. Results The average score for the utility of the course was 4.7 and for the skill stations it was 4.6 on a scale of 5. The qualitative analysis of the feedback emphasized the need for the course before the clinical posting and more skill-based modules rather than lectures. The interactive style of teaching and training in communication using role-play was appreciated. Few suggestions to improve the course were provided. Conclusions Implementing the ACCC needed simulation, interactive discussions, role-play, modified Pendleton's feedback, and reflective exercise that form the basis of a range of educational principles. The blended learning set of objectives of ACCC were the pillars for this successful internship training programme.

ABSTRACT

STUDY DESIGN: Retrospective chart review. OBJECTIVES: The primary aim was to identify the number of patients requiring vasopressors beyond the first week of cervical spinal cord injury (SCI). Secondary objectives were to note the type, duration and doses of vasopressors and any association between prolonged vasopressors use and outcome. SETTING: Neurosurgical intensive care of a tertiary trauma care centre. METHODS: After Ethical approval we retrospectively collected the data of patients of isolated cervical SCI admitted to neurosurgical intensive care from January to December 2017. Vasopressor requirement for sepsis or cardiac arrest was excluded. RESULTS: Out of 80 patients analysed, 54 (67.5%) received vasopressors. The prolonged requirement of vasopressors was observed in 77.7%. Our preferred agent was dopamine (64.8%). We found out that longer requirement (in days) of high dose of dopamine was associated with higher survival (p = 0.03). CONCLUSION: Our results describe a significant portion of cervical SCI patients need ongoing vasopressor to maintain a mean arterial pressure >65 mm of Hg beyond first week. We observed patients who required longer duration of high dose dopamine had a higher chance of survival suggesting some unknown mechanism of high dose of dopamine. This is first such observation, further studies are needed to substantiate.

ABSTRACT

Background: . Effective patient-doctor communication is a key component of patient-centred care, which is one of the six pillars of quality healthcare delivery. Structured and effective communication skills training for healthcare providers is the need of hour in medical education. We assessed the efficacy of role play and simulation in developing communication skills. Methods: . As a key component of an acute critical care course (ACCC), communication skills are taught using role play models and simulation. Live feedback is critical in learning during this course as per the principles of adult learning (andragogy). Quantitative and qualitative data were collected to assess the efficacy of ACCC. Results: . The 19th ACCC was introduced to interns at the All India Institute of Medical Sciences, New Delhi in December 2018. The teaching methodology and objective-oriented structured training in ACCC were much appreciated for training in human factors with emphasis on communication. A positive response was obtained from the candidates 3 weeks after they completed the course to assess whether interns are able to make use of this training in their day-to-day clinical practice amounting to a reliable evidence level of Kirkpatrick's 'return of investment'. Conclusion: . The use of 'role play' to teach communication skills is effective and superior to lecture-based teaching. Further structured and interactive programmes in communication skills training will improve patient care, relatives' satisfaction and the image of medical profession.

ABSTRACT

BACKGROUND: Paroxysmal sympathetic hyperactivity (PSH) is a grave entity affecting patients following traumatic brain injury (TBI). It presents with cyclic and simultaneous fever, posturing, and other symptoms of sympathetic hyperactivity. Lack of diagnostic tests or biochemical markers and its propensity to mimic other common causes of fever in the neurotrauma intensive care unit (ICU) result in clinical dilemmas and management delay. CASE DESCRIPTIONS: We present a case series of four patients (two adults and two pediatrics) with TBI who developed PSH during ICU stay. These patients presented with fever along with variable symptoms of sympathetic hyperactivity. However, the value of serum procalcitonin (PCT) was not elevated, and management of PSH was started. Serial monitoring of PCT helped in differentiating fever due to PSH from sepsis and thus the institution of appropriate and timely treatment of PSH and also helped to use antibiotics rationally. CONCLUSION: The use of serum PCT in differentiating sepsis from systemic inflammatory reaction and its role in the initiation and titration of antibiotics are well described. PSH is a common entity after TBI, causing episodic fever and sympathetic hyperactivity, often confused with infectious pathology. Our report proposes the role of serum PCT in differentiating PSH from infectious etiology and management of two different clinical entities.

ABSTRACT

STUDY DESIGN: Descriptive retrospective. OBJECTIVES: To evaluate the burden of respiratory morbidity in terms of ventilator dependence (VD) days and length of stay in neurotrauma ICU (NICU) and hospital, and to determine mortality in patients with traumatic cervical spinal cord injury (CSCI) in a low middle-income country (LMIC). SETTING: Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences (AIIMS), New Delhi, India. METHODS: A total of 135 patients admitted with CSCI in the NICU between January 2017 to December 2018 were screened. Information regarding age, gender, American Spinal Injury Association (ASIA) impairment scale (AIS), level of injury, duration of VD, length of NICU, hospital stay, and outcome in terms of mortality or discharge from the hospital were obtained from the medical records. RESULTS: A total of 106 CSCI patients were analyzed. The mean (SD) age of patients was 40 (±16) years and male: female ratio was 5:1. The duration of VD, duration of NICU, and hospital stay was a median of 8 days (IQR 1127), 6 days (IQR 1118), and 15 days (IQR 3127) respectively. Mortality was 19% (20/106). The mortality was significantly associated with poorer AIS score, VD, and duration of ICU and hospital stay. All patients were discharged to home only after they became ventilator-free. CONCLUSIONS: The ventilator burden, hospital stay, and mortality are high in patients with CSCI in LMICs. Poor AIS scores, prolonged VD, ICU and hospital stay are associated with mortality. There is a need for comprehensive CSCI rehabilitation programs in LMICs to improve outcome.

ABSTRACT

BACKGROUND: Device-associated infections (DAIs) are an important cause of excessive stay and mortality in ICUs. Trauma patients are predisposed to acquire such infections due to various factors. The prevalence of HAIs is underreported from developing nations due to a lack of systematic surveillance. This study reports the rates and outcomes of DAIs at a dedicated Trauma Center in trauma patients and compares the rates with a previous pilot observation. METHODS: The study reports the finding of ongoing surveillance and the use of an indigenous software at a level-1 trauma center in India. Surveillance for ventilator-associated pneumonia, central line-associated bloodstream infections, and catheter-associated urinary tract infections was done based on standard definitions. The rates of HAIs and the profile of pathogens isolated from June 2010 to December 2018 were analyzed. RESULTS: A total of 7485 patients were included in the analysis, amounting to 68,715 patient days. The rates of VAP, CLABSI, and CA-UTI were respectively 12, 9.8 1st 8.5/1000 device days. There was a significant correlation between device days and the propensity to develop infections. Of the 1449 isolates recovered from cases of DAIs, Acinetobacter sp (28.2%) was the most common isolate, followed by Candida sp. A high rate of multi-resistance was observed. CONCLUSION: Automated surveillance was easy and useful for data entry and analysis. Surveillance data should be used for implementing preventive programs.

ABSTRACT

Chin-on- chest deformity is not uncommon sequelae of ankylosing spondylitis. Apart from difficult airway, several other considerations might include co-existing cardio-respiratory embarrassment, osteoporotic bones, and neurological perturbations. We describe the successful anesthetic management of a case of chin-on-chest deformity with no access to midline neck structures and extremely difficult airway posted for corrective spine surgery.

ABSTRACT

BACKGROUND: Despite advances in perioperative neuroscience, there is low interest among anesthesiology trainees to pursue subspecialty training in neuroanesthesiology. We conducted a pilot survey to assess attitudes about neuroanesthesiology fellowship training. MATERIALS AND METHODS: A confidential survey was distributed to an international cohort of anesthesiology attendings and trainees between January 15, 2017 and February 26, 2017. RESULTS: A total of 463 responses were received. Overall, 309 (67%), 30 (6%), 116 (25%), and 8 (2%) of respondents identified themselves as attendings, fellows, residents, and "other," respectively. In total, 390 (84%) of respondents were from the United States. Individuals typically pursue anesthesiology fellowship training because of interest in the subspecialty, acquisition of a special skill set, and the role of fellowship training in career planning and advancement. Overall, 64% of attendings, 56% of fellows, and 55% of residents favored accreditation of neuroanesthesiology fellowships, although opinion was divided regarding the role of accreditation in increasing interest in the specialty. Respondents believe that increased opportunities for research and greater exposure to neurocritical care and neurological monitoring methods would increase interest in neuroanesthesiology fellowship training. Perceived barriers to neuroanesthesiology fellowship training were perceptions that residency provides adequate training in neuroanesthesiology, that a unique skill set is not acquired, and that there are limited job opportunities available to those with neuroanesthesiology fellowship training. CONCLUSIONS: In this pilot survey, we identified several factors that trainees consider when deciding to undertake subspecialty training and barriers that might limit interest in pursuing neuroanesthesiology subspecialty training. Our findings may be used to guide curricular development and identify factors that might increase interest among trainees in pursuing neuroanesthesiology fellowship training.

ABSTRACT

Cyanotic congenital heart disease (CCHD) is often associated with more than one cardiac anomaly with unique hemodynamic pattern, hence presenting a plethora of challenges to non-cardiac anesthesiologists. Understanding the pathophysiology of the cardiac lesion and constructing a cardiac grid can help in determining intraoperative hemodynamic goals and facilitate smooth perioperative management of such patients. This case report describes the anesthetic management of an infant with dextro-transposition of great arteries (dTGA) with a large atrial septal defect, ventricular septal defect, severe pulmonary stenosis, and patent ductus arteriosus posted for excision and repair of occipital meningocele and highlights the role of cardiac grid in clarifying anesthetic goals and ensuring better outcomes.

ABSTRACT

BACKGROUND: Traumatic brain injury (TBI) is associated with majority of trauma deaths, and objective tools are required to understand the severity of injury. The application of a biomarker like procalcitonin (PCT) in TBI may allow for assessment of severity and thus aid in prognostication and correlation with mortality and outcome. AIMS: The primary objective is to determine the correlation between PCT concentrations with TBI outcomes (mainly in terms of mortality) at intensive care unit (ICU)/hospital discharge. Secondary objectives are to evaluate correlation with associated extra cranial injuries and complications during hospital stay. METHODS: In total, 186 TBI patients aged > 18 years with minimum survival for at least 12 h admitted to the ICU at the level 1 trauma center were prospectively included in the study and divided into two groups: TBI with and without extra cranial injuries. All admitted patients were treated according to the standard institutional protocol. The PCT levels were obtained on admission, on day 2, and 5. Clinical, laboratory, diagnostic, and therapeutic data were also collected. Primary mortality is defined as death related to central nervous system (CNS) injury, while secondary mortality defined as death related to sepsis or extracranial cause. RESULTS: Median PCT levels at admission, day 2, and day 5 in TBI patients with extracranial injuries were 3.0, 0.83, and 0.69 ng/ml. In total, primary mortality was observed in 18 (9.7%) patients, while secondary causes were attributable in 20 (12.3%) patients. Regression analysis for primarily CNS cause of mortality showed PCT cutoff level at admission more than 5.5 ng/ml carried sensitivity and specificity of 75%, but for secondary cause (sepsis) of mortality, PCT cutoff values on day 2 > 1.15 ng/ml were derived significant with sensitivity of 70% and specificity of 66%. No significant association of parameters like length of ICU stay, Glasgow outcome scale (GOS), and primary/secondary mortality with the presence of extracranial injuries in TBI patients as compared with TBI alone was noted. CONCLUSION: This observational study demonstrates the poor correlation between PCT concentrations with outcome at days 1, 2, and 5 post-injury. The predicted relationship between PCT levels and outcome was not confirmed, and that these results do not support the prognostic utility of PCT biomarker in this population for outcome (mortality) assessment in TBI patients with or without extracranial injuries.

ABSTRACT

Central venous catheter (CVC) insertion is a commonly done procedure but associated with some potential complications. In our case, intraoperatively we placed a CVC into the right subclavian vein of the patient for a neurosurgical procedure. Subsequently, in the neurosurgical intensive care unit, on checking the patency of the CVC, only the distal and proximal lumens were working and no backflow of blood was detected from the middle port. A chest X-ray and ultrasound were done immediately, which did not reveal why the middle port was blocked. Later CVC was removed, and on examination of the catheter, we noted an intraluminal fibrin clot and a partial tear near the opening of the middle port. This is an uncommon complication of a CVC insertion that is catheter tear along with fibrin clot occluding the middle port of the CVC, which was detected in time and managed successfully.
